- "The feeling of wanting to crush someone so bad, even if you like that person... Everyone has those feelings, right?"
- — Kaotin —
Kaotin is a young female PC with short golden hair and a long, princess-like gown. She also wears two small wings on her back. In battle, Kaotin wields a Lance. Like her R:1 counterpart, Kaotin's PC is almost identical to Subaru's.
During her brief appearance while encountered as a Chaotic PK, Kaotin displays a rather disturbing personality. She gigglingly claims that she feels compelled to hurt other people, even those she respects of likes as friends. Her modus operandi is to pick a target and stalk that player incessantly, eventually killing them and picking a new target.
Tsukio Kouda (香田月男) is a 25-year-old freelance illustrator living in Kanagawa Prefecture. Earlier in his life when he was a nameless rookie and had too much time on his hands, he started playing online games, becoming obsessed with stalking other players.

Kaotin is a Chaotic PK known as Kaotin in the Shadows. Haseo encounters her as a bounty. It is unknown what becomes of Kaotin after Haseo defeats her. She has very few lines and plays no noteworthy part in the outcome of the plot. Her appearance is essentially a nod to fans of .hack//SIGN.
Kaotin makes a brief appearance at Δ Hidden Forbidden Festival.
